Write an expression that shows how to use the halving and doubling strategy to find [tex]28 \times 50[/tex].

Double of 50 is 100, so 28*100=2800, now half of the answer is 2800/2=1400

Using halving and doubling, we can find that 28 × 50 can be rewritten as 14 × 100 , which equals 1400 . This strategy simplifies the multiplication process. Therefore, 28 × 50 = 1400 .
